Cell Organelles

Front

What is the function of the mitochondrion?

Back

The mitochondrion is known as the powerhouse of the cell, where cellular respiration takes place to produce energy (ATP).

Front

What is the role of the Golgi apparatus in a cell?

Back

The Golgi apparatus is responsible for packaging and shipping proteins and lipids to their destinations inside or outside the cell.

Front

What does selectively permeable mean in relation to the cell membrane?

Back

Selectively permeable means that the cell membrane controls what substances can enter or leave the cell, allowing some to pass while blocking others.

Front

What distinguishes an animal cell from a plant cell?

Back

Animal cells do not have a cell wall or chloroplasts, while plant cells do. Animal cells are generally rounder, while plant cells are more rectangular.

Front

What is the primary function of the nucleus in a cell?

Back

The nucleus directs all cell activities and contains the cell's DNA, which carries genetic information.

Front

What is the function of ribosomes in a cell?

Back

Ribosomes are responsible for protein synthesis, translating messenger RNA (mRNA) into proteins.

Front

What is the role of lysosomes in a cell?

Back

Lysosomes contain digestive enzymes that break down waste materials and cellular debris.

Front

What is the function of the endoplasmic reticulum (ER)?

Back

The endoplasmic reticulum is involved in the synthesis of proteins (rough ER) and lipids (smooth ER), and it also helps in transporting materials within the cell.

Front

What is the difference between rough and smooth endoplasmic reticulum?

Back

Rough ER has ribosomes on its surface and is involved in protein synthesis, while smooth ER lacks ribosomes and is involved in lipid synthesis and detoxification.

Front

What is the purpose of vacuoles in plant cells?

Back

Vacuoles store nutrients, waste products, and help maintain turgor pressure in plant cells.
